How does rapid evolution alter the theory of population ecology?

Increasing evidence suggests the prevalence of rapid contemporary evolution and the importance to consider evolution for understanding and predicting population dynamics. However, it is still unclear how rapid evolution and resultant feedbacks between ecological and evolutionary dynamics (eco-evolutionary feedbacks) alter the existing theory of population ecology. Here, I present an overview of recent findings from theoretical and empirical studies about (1) (de)stabilizing effects of evolution, (2) phase relationships between interacting species densities, (3) the maintenance of variation in fluctuating environments at genetic and population levels, and (4) extinction processes with evolution. Throughout these topics, I would like to emphasize the ongoing synthesis of population ecology and population genetics. Furthermore, I discuss future challenges to deepen our understanding of population, community, and ecosystem dynamics through the lens of eco-evolutionary feedbacks.
